Title: Video recorder with a dynamically tunable tuner
Inventor: SCHULEIN REINHARD DIPL-ING FH
IPC: H03J7/06
Filed: 1988-04-20
Abstract: 2.1 Conventional video recorders having dynamically tunable tuners are elaborate with respect to the technical implementation. In the novel video recorder, a dynamic tuner tuning should also be possible without great technical expenditure. 2.2 For this purpose, a switch-over device, which separates the voltage-controlled oscillator from the RF modulator and connects it as reference oscillator to the input of the tuner for the dynamic tuning of the tuner is connected between the voltage-controlled oscillator of the RF modulator, the RF modulator itself and the tuner. <IMAGE>

Abstract: Disclosed is a collating device for collating the images on a photographic film with those printed on a printing paper from the photographic film while conveying the film and the printing paper. The collating device includes a reading device for reading a frame number for identifying the frame image on the film, and a printing device for printing the frame number which has been read by the reading device on the printing paper on which has been printed the image on the film which corresponds to that frame number. The frame numbers of the film are printed on the printing paper on which have been printed the images on the film. In consequence, the print images on the printing paper are easily made to correspond to the corresponding frame images on the film, and designation of the frames is facilitated.

Abstract: Apparatus for dispensing a liquid charge director composition in a liquid electrophotographic copying machine comprises a charge director reservoir (22) including a pressure cell (23) arranged below the liquid level of the charge director reservoir. The pressure cell has a volume to contain a predetermined amount of liquid charge director composition. The pressure cell is provided with an opening (24) to permit a flow of liquid charge director composition from the charge director reservoir (22) and into the interior (13) of the pressure cell (23) and vice versa. A tubular conduit extends from the interior of the pressure cell to the reservoir (14) that contains the liquid developer composition to provide fluid communication therebetween. A controlled pulse of air is directed into the interior of the pressure cell to force all of the liquid charge director composition within the pressure cell from the pressure cell, with portions of the liquid charge director composition flowing through each of the opening and the tubular conduit. The ratio of the diameter of the opening (24) to the diameter of the tubular conduit (13) is fixed such that the controlled pulse of air causes a preselected amount of liquid charge director composition to flow through the tubular conduit and into the reservoir that contains the liquid developer composition and causes the remaining portion of the liquid charge director composition to flow through the opening and into the charge director reservoir.

Abstract: The present invention relates to an all-dry submersible motor pump with a concordant seal system. In this submersible pump, there is a motor within a motor room, a vertical rotary shaft driven by the motor and connected to a pump means. An air chamber is positioned between the motor room and the water pump means. A airtight disc is provided between the motor room and the air chamber with a central hole for passing through the vertical rotary shaft. A concordant seal means is arranged below the disc and around the central hole. The concordant seal means comprises a fluid-seal means and a pressure equalizing means. The pres­sure equalizing means employing a moist-isolating air envelope for equalizing the pressures on both sides of the disc, cooperates with the shaft fluid-seal means to prevent the moist air from invading the motor room and thereby ensure a dry working condition for the windings of the motor.

Abstract: The invention relates to a method and a device for decontaminating soil layers containing toxic substances by means of a decontaminating medium taking up toxic substances which is introduced into the soil layers by means of a drill pipe, and is removed from the soil layers by suction and is subsequently further processed. To enable selective decontaminating of the soil layers on site without the necessity of excavation of soil using a continuous process with minimal technical effort, decontamination is effected inside a chamber (20) surrounding the drill pipe (1), which is lowered into the soil to be contaminated either together with or separately from the drill pipe (1). It is particularly proposed that, after completion of the individual decontaminating process, at least parts of the chamber used for this are removed from the soil again and placed in an area of soil not yet decontaminated, so that a decontaminating process advancing in a horizontal direction results. Furthermore it is proposed that, depending on the type of soil and behaviour of the toxic substances, the sludge mixture resulting is pumped to a decontaminating plant above ground and that the decontaminated soil obtained here is replaced in the chamber (20). …<IMAGE>…

Abstract: A plurality of intermittent incisions (14, 15) are made in a surface region of a fiberboard (20) to sever fibers without removing them from the surface region. The resultant fiberboard may be molded under heat and pressure to a three dimensional hardboard (60, 70) with high fidelity to the mold and without causing stretch marks, tears or fractures. The fiberboard may be a dry consolidated mass of wet-felted cellulosic fibers. The invention is particularly valuable in the molding of boards made from redwood fibers and other long fibers. 
     The intermittent incisions (14, 15) may be made along one or more lines parallel to or perpendicular to the longitudinal edge of the fiberboard but a grid of incisions along intersecting lines is advantageous. To cut the incisions, the fiberboard (20) is preferably moved on a conveyor belt (21) while an assembly (22) of toothed cutting disks (23) is rotated in cutting engagement with the board. The cutting disks are mounted co-axially on a motor-­driven shaft (24).
